Abstract: 613,366. Casting. SPECIALLOID, Ltd., GRAHAM, E. B., and GARDENER, F. June 24, 1946, No. 18842. [Class 83 (i)] Casting processes ; moulds ; cores, coating cores ; extracting castings.-In a piston casting machine comprising hydraulic rams which operate a main vertically movable core, two horizontally movable core elements for the gudgeon pin bosses and also, through lost motion connections, the two horizontally separable parts of the mould, the rams operating the said core elements are vertically adjustable so that the elements may be brought in the correct position with respect to appropriate mould parts to produce pistons having the gudgeon pin axis at various distances from the open end of the skirt. Side parts 8 of the mould are each connected rigidly with supports 9 slidable on a table or bench 10 by the actuaation of rams in cylinders 11. The table 10 forms part of casting 4, mounted on trunnions 3, and to the base of which is secured a cylinder 5, the ram of which supports and controls the movement of a core member 7. The core elements 18 are each supported on a rod 17 extending through a vertically elongated slot in a plate 16 engaged between lugs 15 on each of the brackets 9. On the rod are provided abutments 19 and 20 spaced so that the motion of the appropriate ram withdraws the core element before the halves of the mould are parted. The cylinders 11 are secured to slotted brackets 21, through which are passed bolts 23 extending through holes 24 in elements 25 depending from the table 10, the cylinders and brackets thereby being adjustable in a vertical direction. The core members 61 for the gudgeon pin bosses are each bored out to receive a tubular element 63 with inlet and outlet ports for cooling water. For cooling and lubrication of the core 7, a dispersion of graphite, or other suitable medium, is sprayed on it as it is withdrawn, from the three nozzles 70, the controlling valve of which is operated by the cooperation of a lever 73 with a roller 75. The mould may be initially heated by the gas jets 60. In a modification for casting pistons with recessed tops, the necessary core element may be suspended from a pivoted standard 56, or operated by a vertically acting hydraulic cylinder. The table 10 is preferably secured to a standard or support by means permitting it to be levelled, while the flow of metal is provided in the desired direction by tilting the casting 4 about its horizontal axis.

Title: A key cutting machine
Inventor: SPAIN ROY CLIFTON
IPC: B23D67/00
Filed: 1968-04-23
Abstract: 1,201,538. Key cutting machine. R. C. SPAIN. 23 April, 1968 [17 July, 1967], No. 19157/68. Headings B3K and B3L. A hand-operated key cutting machine has a holding device 97 for holding a key blank 171 while a broach 47, or a rotary cutting wheel, is driven by a pivoting handle 15 to cut the notches. The holding device 97 is rotatable to a position 22 degrees on either side of a central position to enable the notches in the key to be cut perpendicular thereto or at an angle in each direction, and is locked in its selected position by a spring-biased pin 111. To provide three different depths of cut the twelve teeth 51-62 of the broach 47 are divided into three groups of 4, the handle 15 moving the broach forward one tooth at a time by means of a spring-biased lever 41 engaging with notches 71-82 until a stop-plate 23 engages with grooves 91-93 at every fourth increment of movement of the broach. A hole may be provided in a side plate of the machine to view the side of the broach to ascertain the cutting depth. The key blank is located in a carrier 160 by interengaging studs and notches and the carrier and key blank is mounted in the holding device to allow lateral feeding of the key blank to allow successive notches to be cut. To achieve this the carrier 160 has in its underside a set of rack teeth engaging with a pinion.  During a machining operation rotation of the pinion is prevented by a spring pulling the end of the pinion into an internally-toothed recess. In a modification the cutting may be carried out in a factory installation by rotating cutting wheels. In cutting a key from an existing cut key a guide follows the notches of the existing key while a cutting wheel cuts corresponding notches in the key blank. In this type of operation two holding devices 97 are used.

Title: Improvements in the method of manufacture of flanged articles of paper or like material
IPC: B31B50/59
Filed: 1933-07-06
Abstract: 415,247. Making flanged paper &c. articles. TAYLOR, E. Z., 377, Oraton Street, Newark, New Jersey, U.S.A. July 6, 1933, No. 19171. [Class 100 (ii).] Flanged articles such as box parts, caps, or covers are made by forcing a blank A of paper or like material into a die 6 by means of a plunger 2 eccentrically-mounted on the end of a continuously-rotating spindle 1. The plunger 2 has a slightly less diameter than the inner diameter of the flanged article, and preferably is freely rotatable on its spindle so that due to its eccentric mounting it moves horizontally along the die 6 to roll out the flange and prevent fracture thereof. Where articles of non-circular form are being made, the parts 2, 6 are of the shape required, and the plunger 2 must be rotatable or its spindle 1. Instead of a rolling action, an ironing action is obtained in these circumstances. A spring-pressed toothed ring 9 on the plunger co-operates with a toothed surface 7 on the die 6 so as to keep the edges of the blank A flat as it is drawn into the die. A device 11 is provided for ejecting the articles from the die 6.

Filed: 1973-04-19
Abstract: 1424547 Rolling mills MANNESMANNMEER AG 19 April 1973 [20 April 1972] 19178/73 Heading B3M A rolling mill which is suitable for producing thin-walled tubes with thickened ends includes rolls 10 which are supported between two housings 1 and 5, the housing 5 being rotatably adjustable by a ram 12 to vary the skew angle of the rolls. The roll chocks 9, Fig. 4, in each housing are radially by spindles 18 associated with worm-wheels 20 and worms 24. Additionally, a nut 30 is coupled to each wheel 20 with a desired degree of backlash. By rotating the nut 30, the backlash is taken up and the associated roll is moved inwardly to a desired extent, thereby setting the mill for rolling a normal tube wall rather than a thickened end portion. Movement of the roll in this procedure is controlled by applying pressure to one or other side of a cylinder assembly 28 coupled to the spindle 18. The chocks 9 are normally held in an adjusted position by pivoted levers (Figs. 7-9, not shown) which co-operate with slots in the chocks, the levers being released by hydraulic cylinders when adjustment is to be made. The levers also facilitate rapid dismantling of the roll assemblies.

Class 130 Cigar bunches are transferred from a bunch making apparatus 2, Fig. 1, to a moulding device comprising an intermittently moving drum 16 with mould pockets 18 by a carrier 25 which, after receiving a bunch A, is moved along a guide 6 into position between the drum 16 and movable guide jaws 61 which close to grip the bunch, the carrier 25 being retracted before a plunger 62 moves downwards to force the bunch through the jaws 61 into the pocket 18. The carrier 25 comprises a thin plate, sliding in grooves in the guide rails 6, attached to a block 42 reciprocated through links 43, 44, 47 by a member 53 attached to one of the reciprocating rods 52 which actuate the magazine 51 feeding tobacco into the aprontype bunch rolling mechanism 2 from which the completed bunch is discharged on to the plate 25. The drum 16 is moved stepwise by an oscillating lever 32, Fig. 3, carrying a claw 28 actuated radially by a face cam 24 and the jaws 61, urged apart by a spring 67, Fig. 4, are moved inwards by cams 81, Fig. 3, carried by the operating arm 69 of the loading plunger 62 which is reciprocated through linkage 68, 71, Fig. 1, by a face cam 78. The carrier plate 25 may be slightly concave and may have associated therewith a clamping means 85, Fig. 8, which clamps the end of the bunch A during transfer. The member 85 is pivoted on the block 42 and is connected by a link 89 to the carrier operating lever 43 which is connected to the block 42 by a pin 27 sliding in a slot 87. At the end of retraction the block 42 contacts a stop and further movement of the member 43 in the slot 27 causes the finger 85 to lift to permit entry of a bunch A. Initial movement of member 43 to the left first moves finger 85 to clamp on the end of the bunch and then moves the block 42 and'carrier 25 to the feeding position above the pocket of drum 16. Movement of member 43 to the right releases the clamp 85 from the bunch before retracting the carrier 25. In a modification, Fig. 12, the clamp 85 is replaced by a suction device 91. Specifications 234,044 and 279,564 are referred to.
